2022-04-28target/arm: Advertise support for FEAT_TTLPeter Maydell
The Arm FEAT_TTL architectural feature allows the guest to provide an optional hint in an AArch64 TLB invalidate operation about which translation table level holds the leaf entry for the address being invalidated. QEMU's TLB implementation doesn't need that hint, and we correctly ignore the (previously RES0) bits in TLB invalidate operation values that are now used for the TTL field. So we can simply advertise support for it in our 'max' CPU.

2022-04-28target/arm: Use field names for accessing DBGWCRnRichard Henderson
While defining these names, use the correct field width of 5 not 4 for DBGWCR.MASK. This typo prevented setting a watchpoint larger than 32k.

2022-04-28target/arm: Disable cryptographic instructions when neon is disabledDamien Hedde
As of now, cryptographic instructions ISAR fields are never cleared so we can end up with a cpu with cryptographic instructions but no floating-point/neon instructions which is not a possible configuration according to Arm specifications. In QEMU, we have 3 kinds of cpus regarding cryptographic instructions: + no support + cortex-a57/a72: cryptographic extension is optional, floating-point/neon is not. + cortex-a53: crytographic extension is optional as well as floating-point/neon. But cryptographic requires floating-point/neon support. Therefore we can safely clear the ISAR fields when neon is disabled. Note that other Arm cpus seem to follow this. For example cortex-a55 is like cortex-a53 and cortex-a76/cortex-a710 are like cortex-a57/a72.
